Abstract

As a high-precision angular rate sensor, high-precision fiber optic gyroscope (HP-FOG) can be used for space positioning, strategic missile guidance and submarine navigation. With the further improvement of the demand for navigation accuracy under deep and open sea conditions and satellite rejection conditions, the goal is to manufacture FOG with higher accuracy and sensitivity. The noise of FOG has become the key to restrict its application in high-precision field. In this paper, the noise source of FOG is analyzed, and the method of using semiconductor optical amplifier to suppress relative intensity noise and feedback adjustment to reduce noise is given. In theory, we propose a scheme of FOG using three photon states as light source to improve the detection sensitivity. In theory, this scheme can realize three times super-resolution measurement.
